A Variational Characterization of -Mutual Information and its Application to Computing -Capacity
Akira Kamatsuka, Koki Kazama, Takahiro Yoshida
-mutual information (-MI) is a wide class of information leakage measures, where is a pair of monotonically increasing function and a concave function , whi…
A New Algorithm for Computing -Capacity
Akira Kamatsuka, Koki Kazama, Takahiro Yoshida
The problem of computing -capacity for is equivalent to that of computing the correct decoding exponent. Various algorithms for computing them have been proposed, such as…
Alternating Optimization Approach for Computing -Mutual Information and -Capacity
Akira Kamatsuka, Koki Kazama, Takahiro Yoshida
This study presents alternating optimization (AO) algorithms for computing -mutual information (-MI) and -capacity based on variational characterizations of -MI using a…
New Algorithms for Computing Sibson Capacity and Arimoto Capacity
Akira Kamatsuka, Yuki Ishikawa, Koki Kazama +1
The Sibson and Arimoto capacity, which are based on the Sibson and Arimoto mutual information (MI) of order α, respectively, are well-known generalizations of the channel capacity…
Prediction Algorithms Achieving Bayesian Decision Theoretical Optimality Based on Decision Trees as Data Observation Processes
Yuta Nakahara, Shota Saito, Naoki Ichijo +2
In the field of decision trees, most previous studies have difficulty ensuring the statistical optimality of a prediction of new data and suffer from overfitting because trees are…
An Algorithm for Computing the Stratonovich's Value of Information
Akira Kamatsuka, Takahiro Yoshida, Koki Kazama +1
We propose an algorithm for computing Stratonovich's value of information (VoI) that can be regarded as an analogue of the distortion-rate function. We construct an alternating opt…
